Insulation
Okoguard is Okonite's registered trade name for its exclusive ethylene-propylene rubber (EPR) based, thermosetting compound, whose optimum balance of electrical and physical properties is unequalled in other solid dielectrics. Okoguard insulation, with the distinctive red color and a totally integrated EPR system, provides the optimum balance of electrical and physical properties for long, problem free service.

The triple tandem extrusion of the screens with the insulation provides optimum electrical characteristics.

Jacket
The Okolon jacket on this cable is a vulcanized chlorosulfonated polyethylene based compound which is mechanically rugged, flame, radiation, and oil resistant.

Applications
Okoguard Shielded-Okolon power cables are recommended for use as feeder circuits in utility generating plants, in distribution applications and for primary circuits.

Type MV cables may be installed in wet or dry locations, indoors or outdoors (exposed to sunlight), in any raceway or underground duct, directly buried if installed in a system with a grounding conductor in close proximity that conforms with NEC Section 310.7, or messenger supported in industrial establishments and electric utilities. Sizes 1/0 AWG and larger may also be installed in cable tray.

Refer to Table 310-77 for 8kV ampacities

(4) Ampacities based on single Type MV-105 5kV conductors, or single conductors twisted together (triplexed, quadruplexed, etc.), size 1/0 AWG and larger, installed in uncovered cable tray in accordance with Section 318-13 of the NEC at an ambient temperature of 40°C and a conductor temperature rating of 105°C. In accordance with NEC Section 318-13(b) the ampacities are 75% of the values given in NEC Table 310-69 (copper conductors). Where the cable tray is covered for more than six feet with solid unventilated covers, the ampacities shall not exceed 93% of the values shown above. Refer to Table 310-69 for 8kV ampacities.
